Stop! I can only get so erect!
TheUSSRegularity
Why are they not using coolant?
xSocksMan
You should be ashamed of yourself, there was no end result...I just wasted the last minute waiting for an end result you filthy swine! Kys
songbringer
damn, those are some deep cuts.
EddieWeeks
That is not aluminum... that is steel !!!! Very impressive

CNC machines - the wonders of the 1980s...

But when they fuck up, they fuck up real bad

Needs more lube!
CallMeMuppet
I operate these everyday. You'll grow to hate them. But at least I feel like a fucking boss when I fix one that has broken down.
latecommenter
That's not dickbutt...
ArtificialAardvark
Why is no lubrication used?
TheNamiKage
Can't help but feel there was a better way to make that part though, it's a lot of wasted material.
Shadowdragonss
From what I heard they're using that material to advertise the endmill, they're not really making a part .
SweatshirtJones
What is it?!
Andrewwashere
As a toolmaker it pays to remember that most people never actually see this. It's just everyday stuff for others though
HorseonaBike
'Goggles people! Goggles!'

"Ooooh yeah, baby, show me some of that slotting around - let's do some plunging, mmm..."
DidgeryDrew
Seems like a lot of waste. Why not cast it instead?
DontLikeAnything
Can't you collect the cuttings, though?
Shadowdragonss
No, they typically use coolant to disapate the heat from the endmill, what they're doing is a tech demo, not really making a part.
EmilinRose
needs banana for scale

+1 for the duration given

Sure was nice of them to put the text where all the metal is being flung, just to make it harder to read.
AmityvilleHodor
Give me a hammer, a chisel, and 5 million years and I can do this by hand...
SnarkyScience
I don't care how long, you can never achieve the tolerances here.
Imageurgh
He's accounting for the jillion scrapped parts, dawg
hobogiraffe
At first I thought you said hamster, I was so confused.
Konargus
Why do you need a chisel and a hammer if you're planning to do this by hand?
gotcl2
Your finger nails and ten million and you’ve got a deal
Drixelix
5 mil? Youre optimistic
AmityvilleHodor
I have a go-getter attitude, and a LOT OF elbow grease... I use 10 sticks of deodorant a day
hungitalianohwaitthisisntgrindr
wtf is a cnc machine and wtf is that thing it just carved?
pyr666
"computer numerical control", it cuts (usually metal) things by following pre-programmed movements.
hungitalianohwaitthisisntgrindr
cool. now wtf is that thing it’s making?
pyr666
it may well be nothing. I think this is a tech demo.
Heatseeker49
I was really waiting for a c&c'd dick butt. damn
SexuallyAwkwardDonkey
Thought I'd throw this out there, CNC (Computer Numerical Control) but I get why it sounds like c&c
Heatseeker49
Now I know.
pingzing
These are demos for the end mills. Not the machines themselves.
CptCaboose
yeah cause i was doing this kind of shit in my first CNC class where i would manually type in G-code. ain't no pros here...
pingzing
I remember. Programs by hand, trig bolt holes. Ug. I am out of programming these days.
ProffesorGoogle
Still it's pretty impressive
pprmach3t3
They do say "demonstrate" in the title
hypnotictommy
On top of that, they cannot sustain this type of machining for long before needing to be replaced.
BigAZNMan
It's definitely missing the cutting/ cooling oil.
Evilgerman3000
Using hss in hsc the air cools enough for some things.
Gulch1969
You'd be surprised how long they can last
rumandbass
that's what she said about the guy she told you not to worry about.
barnwolf
I think I'd also be surprised at how expensive they are to buy/run/maintain/replace bits/sharpen bits...
Gulch1969
It all depends really, some brands like Garr are good quality and a good price. 1/2" 5 flute bull endmill will run you about $60.
pingzing
Yep, that is why demos like that are cool. Work out the tool costs and you would be backing the fees down. Depends on who pays the bills
AnonoMouser
fees are feed rates? if I tried that it'd wreck my mill, which would be another cost.
AliitOriShyaTalDin
Yeah, the average mill and tool holders aren't rigid enough for this, that looks like a mill chuck to me, most shops use ER collets at best.
gerf
Obviously feedrates. And he'd be using coolant.
pingzing
Yes, sorry feed rates
NewmarketMTB
Are those sparks normal?
Urgalicity
Only if you are really stupid
StormBurnX
Yes and no. Most tips/machines need a desperately huge amount of lubricant. This is showing off -amazingly good- tips that don't melt down.
Bob64
Good 'ol cuntsten targlide.
iamalreadyaghost
Usually they would use coolant
fastmover45
they are tungsten car glide (AVE told me)
GuW69
It's "pungsten har glid" in Swedish
ej255
Pretty sure it's cuntstain tar glide, skookum as frig.
nowlater123
Yes, but it is an indication of pushing an end mill really hard.
eldarthe
Those are some really deep cuts and unless the video is sped up it is going really fast
BradleyNorby
Or wearing out
SexuallyAwkwardDonkey
In other words, rip that cutter, and possibly mill
PleaseAMArelatedtomachining
not that mill
coop61gt
First time I've ever seen aluminum spark like that.
thereverseapachemaster
Because it is not aluminum.
coop61gt
What metal then? I've never seen SS spark either.
thereverseapachemaster
Could be alloy steel or stainless. Many stainless types have carbon in them.
SherMattLockSmith
Normally these operations would be done under flood cooling to extend the life of the tool by keeping everything cool.
Mistruths
That or they'd go a lot slower.
grumpykraut
Could they even go that fast without cooling or is that clip sped up? I guess that's aluminium but still...
thereverseapachemaster
It is stainless or alloy steel. See blue chips. Almunimum would not spark either.
grumpykraut
Damn you're right. Forgot all about that since my machining course back in school.
